Flat welding flanges connect pipes with matching diameter and wall thickness through flat welding. Butt welding flanges feature a recess slightly larger than the pipe outer diameter, allowing pipe insertion before welding.
Flat welding flanges offer simpler construction with reduced material usage, making them suitable for medium to low pressure applications. Butt welding flanges provide superior rigidity and sealing performance for high-pressure systems.
Butt welding flanges utilize die punching or casting methods to create half-ring elbows, subsequently welded together. Flat welding flanges employ gaskets made from plastically deformable materials with adequate strength.
